Door fly screen broken!

[debham]

Hi there
Advice needed please. We are just chilling in the van when there was a bang and it appears that the mechanism in the door fly screen has broken......is it mendable or is replacement required? The van is a Lunar Si 2009
Thanks

My ACE Diplomat one detaches itself from the door frame, but noiselessly !
Needs a push back each time. Hopefully, a warranty item to fix. Only used once/
